About FUSO
FUSO INTERNATIONAL SA, headquartered in Plan-les-Ouates near Geneva, is a manufacturer of quick-disconnect couplings for the liquid cooling of data centers. The product range includes the UQD series to OCP UQD v2, the blind-mate series UQDB and MQDB as well as mini-QD couplings for compact direct cooling architectures. The bodies are predominantly made of 316L stainless steel, seals are made of EPDM; series production takes place on multi-spindle lathes followed by assembly. Founded as a spin-off of a globally active Tier-1 group of the automotive industry specializing in fluid management, FUSO transfers the production and testing standards established there to liquid-cooling manufacturing. Production and assembly sites are located in France, China and Portugal, while the R&D center in Portugal develops the product series and implements customer-specific modifications. Each series is tested, among other things, with aging tests and helium leak tests; delivery is worldwide, supported by regional warehousing.
